Admin Keepalive timer

[alhakeem2001]

Guys I've installed the Admin keepalive timer on my zc 1.5.1, Template template333 , But once I get warned that my time has been expired ( If I couldn't get the first warning-in case if I was away of computer ! ), I had to log in again, so once I fill-in my admin and pass words to go into my admin panel I get a blank page and if I remove in the URL at the top of my brawser all the text after my admin's name, I could get into my admin panel again and so far I could go every where in there except I couldn't add a new product as I'm getting the blank page again once I click on add a new product ! the log file is pointing to this line in that page > admin/keepalive.php on line 12
Which is: header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
and the whole log's info is:

PHP Warning: Cannot modify header information - headers already sent by (output started at /home1/public_html/newadmin/includes/keepalive_module.php:34) in /home1/public_html/newadmin/keepalive.php on line 12


Is that happening because I changed the time format from the US ( M,D,Y) to GB ( D,M,Y)? and how to fix the problem with the blank page ?

It hasn't even been a whole day yet. Give the people who understand all the code some time to see your question and come up with some ideas, or post some further info on what you have been doing to try to diagnose the issue.
